A field experiment was conducted at Rice Research Unit, Bapatla during Kharif, 2013 to observe the performance of hybrids under Krishna Western Delta. The experiment was laid out in Randomized Block Design with four replications. The treatments are 5 rice hybrids like DRRH2, DRRH3, KRH2, PA6201 and CRHR32. The results of study revealed that the hybrids exhibited superiority in respect of different growth parameters like plant height, number of tillers per hill, panicle length grain yield and straw yield. Among various tested rice hybrids, maximum grain yield (6408 kg/ha) and straw yield (7178 kg/ha) were recorded in PA6201 which might be due to better growth parameters and yield components of hybrids.

The aim of this study was to evaluate the influence of planting density and cultivar of soybean on yield components in the southeast Amazon. The experiment was carried out in an Oxisol, with a randomized block design in a 2 x 4 factorial scheme. The treatments were two soybean cultivars (BRS 9090 RR and BRS 8990 RR) and four planting densities (13, 15, 18 and 20 plants m-1), with three replications. First pod insertion height (IFP), plant height (H), number of pods per plant (NPP), grain yield (Y) and weight of 100 grains (W100) were evaluated. The insertion height of the first pod showed a tendency of increase with the increment of plants per linear meter for cultivar BRS 8990 RR, different of the behavior observed for the cultivar BRS 9090 RR, which only showed difference when the density of 300.000 plants ha-1 was tested. For plant height, among soybean cultivars, there was only difference in D400, with BRS 8990 RR showing a maximum height of 83.3 cm, 21% higher than BRS 9090 RR. When evaluated under D350, BRS 8990 RR showed an increase of 13% in the number of pods compared to BRS 9090 RR. Both cultivars showed linear behavior for the grain yield, increasing according the plant population, with the highest grain yield obtained under the density of 400.000 plants ha-1 (4527.3 kg ha-1). The weight of 100 grains was not influenced by any variation factor.

This study was conducted during summer 2015 at Regional Agriculture Research Station, Dipayal, Doti, Nepal to estimate the genotypic and phenotypic variability, heritability, genetic advance and correlation on grain yield and yield associated traits using 26 advance genotypes of lowland irrigated rice. Analysis of variance revealed the existence of significant difference for days to flowering, maturity, plant height, panicle length, thousand grain weight and grain yield. High heritability was estimated for days to flowering (0.88), maturity (0.79), thousand grain weight (0.48) and plant height (0.43) suggesting these traits are under high genetic control. High phenotypic variation was observed for grain yield (24.87%), number of grains/panicle (22.45%), number of panicles/m2 (20.95%) and straw yield (20.75%) while grain yield had medium (12.02%) and remaining traits showed low genotypic coefficient of variation (<10%). High phenotypic coefficient of variation estimated as compared to genotypic coefficient of variation showed environmental influence on the expression of traits. Grain yield (11.98) and days to flowering (10.32) showed medium and remaining traits sowed low genotypic advance as percent of mean. High to low heritability with moderate to low genotypic advance as percent of mean suggested these traits were governed by non additive gene thus direct selection is not beneficial. Further improvements on yield potentiality and yield traits on these genotypes are suggested by creating variation and selection. Panicle length (r = 0.230), days to flowering (r = 0.247), effective tillers (r = 0.488) and straw yield (r = 0.846) manifested significant positive association with grain yield indicating that yield can be increased if selection applied in favor of those yield components.

The number of seedlings per hill of rice plants affects the level of productivity , the use of seeds per hill with the right amount of rice production. This research aims to determine the effect of the number of seeds/clump on the growth and production of rice. Research using randomized block design (RBD) consists of five treatments with four replications. The treatments tested were: A (1 seedling/hill), B (3 seedling/hill), C (5 seedling/hill), D (7 seedling/hill), and E (9 seedling/hill). The seeds used are Batang Piaman variety, 25x25 cm spacing. The experiment sites in lowland farmers Lubuk Minturun Sungai Lareh village, Koto Tangah district, Padang city, West Sumatra province on wed season 2009/2010. Fertilizer is given as 150 kg Urea, 100 kg SP36 and 75 kg KCl per hectare. Urea and KCl are given three times, with brocasting system at 7, 28, and 45 Days After Planting (DAP), while the SP36 is given at 7 DAP combined with Urea and KCl. The results showed the treatment number of seedlings provide significant effect (P<0.05) on the number of grains per panicle and grain yield. However, no significantly effect (P<0.05) on plant height, maximum number of tillers, number of productive tillers, panicle length, percentage of empty grains, and weight of 1000 grains. The use number of seedlings less than five seedling per hill produces the high number of seeds per panicle and grain yield per hectare. Based on these results it can be concluded that the number of seed on the rice crops are not more than five seedling per hill. Keywords: efficiency , number of seeds , production, lowland rice.

An experiment was conducted in the Agriculture Field Laboratory, Noakhali Science and Technology University (NSTU) to evaluate the effects of age of seedlings on the yield and growth performance of transplanted Aus (T. Aus) rice variety from April 2019 to July 2019. The experiment was carried out assigning four age of seedlings (T1 = 22-day old, T2 = 24-day old, T3 = 27-day old, T4 = 30-day old) and two rice varieties (V1 = BRRI dhan83, V2 = BRRI dhan65). The experiment was laid out in a Randomized Complete Block Design with three replications. In case of variety, the highest plant height (102.108 cm), the highest grain yield (2.643 t/ha), and the highest harvest index (32.317%) were obtained in BRRI dhan83 where the lowest plant height (87.804 cm), the lowest grain yield (2.431 t/ha) and the lowest harvest index (32.068%) were obtained in BRRRI dhan65. The age of seedlings had significantly affected total tillers/hill, effective tillers/hill, panicle length in T. Aus rice variety. The highest plant height (98.16 cm), straw yield (6.122 t/ha), the maximum number of effective tillers/hill (15.347) were obtained in 24 days old seedlings. The highest grain yield (2.634 t/ha) was obtained from 27 days old seedlings, and the highest harvest index (33.88%) was obtained from 22 days old seedlings. The lowest grain yield (2.429) was obtained from 24 days old seedlings, and the lowest panicle length (13.753 cm), harvest index (30.467%), and the minimum number of effective tillers/hill (13.753) were obtained from 30 days old seedlings. The lowest straw yield (5.075 t/ha) and plant height (93.16 cm) were obtained from 22 days old seedlings. In case of interaction, the highest plant height (104.667 cm) and the harvest index (34.86%) were observed in BRRI dhan83 at 27 days old seedlings. The highest straw yield (5.805 t/ha) was observed in BRRI dhan65 at 30 days old seedlings. The maximum number of effective tillers/hill (18.519) was observed in BRRI dhan83 at 24 days old seedlings. The highest grain yield (2.94 t/ha) was observed in BRRI dhan83 at 22 days old seedlings. The lowest plant height (80.67 cm) was observed in BRRI dhan65 at 27 days old seedlings. The minimum number of total tillers/hill (17.01) was observed in BRRI dhan83 at 22 days old seedlings; lowest panicle length (20.78 cm), the minimum number of grains/panicle (68.07) were observed in BRRI dhan65 at 24 days old seedlings; 1000 grains weight (22.76 g), the lowest grain yield (2.18 t/ha) were observed in BRRI dhan83 at 24 days old seedlings; the lowest straw yield (4.54 t/ha) was observed in BRRI dhan65 at 22 days seedlings old and lowest harvest index (29.09%) were observed in BRRI dhan65 at 30 days old seedlings. Based on the above results, it may be concluded that almost all of the yield and yield contributing characters of T. Aus rice performed best under the interaction between age of seedlings 22 days old seedlings and the variety BRRI dhan85.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.

ABSTRACT: The objective of this study was to evaluate the plant and fruit characteristics in advanced lines of Jalapeño pepper for mechanical harvesting. Thus, two experiments were carried out in the field. Experiment I (2015) was conducted as a randomized block design (three replications and eight plants per plot) and Experiment II (2016) in a completely randomized design (five replications and ten plants per plot). In 2015, lines CNPH 30,112, CNPH 30,118, CNPH 30,147, CNPH 30,159, CNPH 30,183, and CNPH 30,245 were evaluated, together with the control ‘BRS Sarakura’. Significant differences were detected for fruit and plant characteristics (P<0.05). Lines CNPH 30,118, CNPH 30,147, CNPH 30,159, and CNPH 30,245 were selected based on plant height and height of the first bifurcation, earliness, and yield. They were evaluated again in 2016, together with ‘BRS Sarakura’ and ‘Jalapeño Plus F1’ as controls. In 2016, CNPH 30,159 and CNPH 30,118 were selected due to their potential for mechanical harvesting. They were evaluated for height of the first bifurcation (>10cm), large fruits (11 cm x 4 cm), high pulp firmness (11 N), wall thickness (about 5mm), and content of capsaicinoid substances (>50,000 SHU). Selected lines are undergoing additional field evaluation for mechanical harvesting with the Etgar Moses 1010 pepper harvester.
